Abstract

The invention provides a method for processing the channel quality report of a backhaul link, comprising the following steps: coding the generated channel quality report to obtain the coded information, wherein a relay station determines the amount of the coded information according to the format of a physical uplink control channel (PUCCH) for bearing the channel quality report and the modulation mode of the information of the channel quality report or the configuration indication of a base station; scrambling the coded information to obtain scrambled sequence, then modulating the scrambled sequence to obtain modulated complex value symbol sequence and then carrying out frequency domain extension to obtain the complex value symbol sequence after frequency domain extension; and mapping the complex value symbol sequence after frequency domain extension to the PUCCH physical resource configured by the system. The invention also provides a device for processing the channel quality report of the backhaul link. The method and the device effectively realize that the relay station bears the channel quality report of the backhaul link on the PUCCH and transmits the channel quality report to the base station.

Description

technical field [0001] The present invention belongs to the field of mobile communication, and in particular, relates to a method and device for processing a channel quality report of a backhaul link (Backhaul Link). Background technique [0002] Relay technology, as an emerging technology, has attracted more and more attention and is regarded as the key technology of B3G / 4G. Since future wireless communication or cellular systems require perfect network coverage and support for higher-speed transmission, this poses new challenges to wireless communication technology. At the same time, the cost of system construction and maintenance is more prominent. With the increase of transmission rate and communication distance, the problem of battery power consumption also becomes prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology, the traditional single-hop link can be divided into m...
